Ahead of the US quintet's upcoming concert here at the end of the month, M looks at why girls love Tedder, and why boys want to be like him.

SONG MASTERMIND

When he's not fronting OneRepublic, Tedder is literally a music-making machine for A-listers, with a knack for penning punchy pop hooks.

Songs he has produced and written include Adele's Rumour Has It, Beyonce's Halo, Leona Lewis Bleeding Love and Kelly Clarkson's Already Gone.

And just to show how naturally talented he is, he creates all these melodies without breaking a sweat.

"To be honest, it's like playing video games for me. I'm staring at a (digital-audio software) Pro Tools screen, moving around sounds and samples," he told New Zealand-based news site Stuff.

To Tedder, inspiration is everywhere. "With iPhones, nobody has an excuse for writer's block. If you're at (supermarket) whole foods getting your green tea extract and you have a melody, you just drop it into your voice memo and save it for later," he told The Hollywood Reporter.
